NFS4 id fixes

I was having a problem with ids on an NFSv4 client:

$ ls -l /r1/bob/
drwxr-xr-x  2 4294967294 4294967294 4096 2011-05-14 19:29 junk
drwxr-xr-x  2 4294967294 4294967294 4096 2011-01-30 02:14 junk2
drwxr-xr-x 14 4294967294 4294967294 4096 2011-05-14 16:31 unsorted_junk

After fumbling around for a bit, here is the solution I'm running with now.

On both the server and the client, add this to /etc/idmapd.conf:

[Translation]
Method = nsswitch

On the client, add this /etc/rc.local:

service idmapd start
umount /r1
mount /r1

Now we're all good:

$ ls -l /r1/bob/
drwxr-xr-x  2 bob bob 4096 2011-05-14 19:29 junk
drwxr-xr-x  2 bob bob 4096 2011-01-30 02:14 junk2
drwxr-xr-x 14 bob bob 4096 2011-05-14 16:31 unsorted_junk
